The UNPROTECT command, whose syntax is

	.UNPROTECT filename

allows any logged-in user to change the protection of any file on the disk to
005, which allows any logged-in user access to the file.  The use of the command
is logged on the console terminal and in the file UNPROT.LOG[1,2], which is
otherwise not writeable and cannot itself be unprotected.  The command is
intended as a last-resort emergency technique for legitimate access to protected
files, and its misuse is a serious offense.  User file directories cannot be
unprotected, and a protected directory will prevent access to any of the files
in it.
